Just dikes and water on the youngest part of Holland. Flevopolder is the largest man-made island in the world constructed in the 1950ies and 60ies. It is the latest large addition of new land to the Netherlands and sits in the vast artificial lake crated by the Afsluitdijk. The history and details are covered in this clip. Along the circumference is a biking and hiking path of 145 km. A section is shared with the Markermeer Loop, also an FKT route. It is very popular and you can expect lots of traffic in the summer moths. The island is a preferred weekend and summer holiday destination offering great beaches, surfing and other sports.
